Letters Patent No.110,106, dated December 13, 1870.

. IMPROVEMENTIN BARRE-L CH'AMFERING vAND CROZING-MACHINE.

The Schedule referred to in these Letters Patent and making parl: of the same.

/ To all lwhom it may concern Be it known that we, TRUMAN M. ANNIs and THOMAS B. LUCE, of Linden, in the county of Genesee and in the State of Michigan, have 'invented certain new and useful Improvements in Barrel Obamferingand Grozing-Machine; and do hereby declare thatthe following is afull, clear, and exact description' thereof, reference being had to the accompanying drawing and to the letters of reference marked there-on making apart of this specification.

The nature of our invention consists in the construction and arrangementof a machine for chamfering and crozing barrels, as will be hereinafter fully set forth.

In order -to enable others skilled in the art to which our invention appertains 'to-make and use the same, we will now proceed to describe its construction and operation, referring `to the annexed drawing, in which-- Figure 1 is a -front elevation of our machine and Figure 2 is an enlarged plan view ofthe revolving carriage upon which the chamfering and crozingf knives move.

A represents the frame of my machine, in which, at a suitable height, is placed the circular stationary guide B for the upper end of the barrel.

In the lower portion of the. frame is a platform, C, upon which the barrel is placed.

This platform is on each side provided with a rod, a, which runs up in guides on the inner sides, and close to the frame A.

Around the rods a aare spiral springs, b b, which hold theplatform up s o that the knives may perform their work properly.

' Across 'the upper end of the frame A is a shaft, D, turned by a crank, E, at one end, and at the other end provided with a cog-wheel, G, which gears with and communicates motion to a pinion, d, upon a short shaft which carries the ily-wheel H.

Upon the shaft Dthere is a pinion, e, which gears with a cog-wheel, I, upon another shaft, and on this shaft is still another pinion gearing with another cogwbeel, J upon a shaft, K, thus 'communicating motion to the same.

On this shaft K are two cams, L L, which operate I that the upper end ,of the barrel will project through the guide B. y

It will be seen that in accordance with the construction of the gearing-connecting the shafts D and K, it becomes necessary for `the former to perform a certain number of revolutions before the latter cornpletes .one revolution, for a purpose that will be presently` described.

On the shaft D there is also a miter-wheel, M, which gears with a unter-pinion, j, upon the upper end .of a vertical shaft, g, which passes through a hub, N, formed in the center of a cross-bar in the frame.

On the lower end of the shaft g is secured a horizontaljcarriagc, O, which thus, through the wheel- M and pinion f, obtains a rotary motion.

Above this carriage, on the shaft g, are cnt screwthreads, in which meshes a toothed-wheel, P, having'its journal-bearings on the carriage 0.

Upon each journal of the wheel P (or on each end of the shaft upon which it is placed) is attached a crank-wheel, h 71'.

The wheels h h' are, by pitruen 7e k', connected with sliding blocks, in m', which move in grooves on the carriage.

The block m has the chamfering-knife It attached to it, while the block m carries the crozing-knife S.

When the machine is'in operation the knives It S perform their work, the carriage O describing a series of revolutions and the knives moved by the screw` shaft g and toothed-wheel Ii The knives recede as soon as their work is porformed, and then the cams L L operate upon the rods a. a. to lower the platform O'with the barrel, as `above mentioned.

The pitmen Is k' may be shortened or extended, to suit large or small barrels.

Having thus fully described our invention,

XVhat we claim as new, and desire to secure by Let# ters Patent, is

1. The arrangement of the shaft D, crank E, cogwheel G, pinion d, ily-wheel H, pinion c, cogwheels I J, vshaft K,'and cams. L L, all substantially as shown and described.

2. flhe arrangement of the platform C, rods a a, and spiral springs b b, in combination with the cams L L upon the shaft K, said shaft being revolved by vmeans of the gearing herein described, as and for the purposes set forth. Y

- In testimony that we claim the foregoing, we have hereunto set our hands this 5th d ay of October,l 1870.
